Abstract
This paper reports the results of the experimental investigation on the mechanical behavior of wooden beam joints. Two types of Japanese traditional joint and a new type of joint were tested under the application of bending, shearing and tensile load respectively. A traditional joints, named Okkake-daisen, showed superior behavior than others in tension as well as in bending. Another traditional one, Koshikake-kama, is rather better against shearing force but weeker in tension and in bending. The new joint proved itself the best in mechanical behavior against shearing force and next to Okkake-daisen under bending load and tensile load.
